I need an eyepiece for the Aquatica Nikon n90 housing. I cannot see through the housing/lens of the camera. Can anyone supply some help at all? Thanks.

I, too, needed a boost in magnification. I use the Nauticam straight viewfinder with the Aquatica housing and am very happy with it. It was a little scary changing the viewfinder the first time (like a lot of other first time stuff). I am comfortable now and remove the viewfinder for travel. It packs better that way. Hope this helps.
